Struct rusmpp::codec::command_codec::CommandCodec

pub struct CommandCodec;

A codec for encoding and decoding SMPP PDUs.

Only available when the tokio-codec feature is enabled.

Usage

use futures::{SinkExt, StreamExt};
use rusmpp::{
    codec::command_codec::CommandCodec,
    commands::{
        command::Command,
        pdu::Pdu,
        types::{command_id::CommandId, command_status::CommandStatus},
    },
};
use tokio::net::TcpStream;
use tokio_util::codec::{FramedRead, FramedWrite};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let stream = TcpStream::connect("34.242.18.250:2775").await?;

    let (reader, writer) = stream.into_split();
    let mut framed_read = FramedRead::new(reader, CommandCodec {});
    let mut framed_write = FramedWrite::new(writer, CommandCodec {});

    let enquire_link_command = Command::new(CommandStatus::EsmeRok, 0, Pdu::EnquireLink);

    framed_write.send(&enquire_link_command).await?;

    while let Some(Ok(command)) = framed_read.next().await {
        if let CommandId::EnquireLinkResp = command.command_id() {
            break;
        }
    }

    Ok(())
}

Trait Implementations

impl Decoder for CommandCodec

type Item = Command

The type of decoded frames.

type Error = DecodeError

The type of unrecoverable frame decoding errors.

fn decode( &mut self, src: &mut BytesMut ) -> Result<Option<Self::Item>, Self::Error>

Attempts to decode a frame from the provided buffer of bytes.

fn decode_eof( &mut self, buf: &mut BytesMut ) -> Result<Option<Self::Item>, Self::Error>

A default method available to be called when there are no more bytes available to be read from the underlying I/O.

fn framed<T>(self, io: T) -> Framed<T, Self>

where T: AsyncRead + AsyncWrite, Self: Sized,

Provides a Stream and Sink interface for reading and writing to this Io object, using Decode and Encode to read and write the raw data.

impl Encoder<&Command> for CommandCodec

type Error = EncodeError

The type of encoding errors.

fn encode( &mut self, command: &Command, dst: &mut BytesMut ) -> Result<(), Self::Error>

Encodes a frame into the buffer provided.
